Steve Jobs called Tim Cook, the new CEO of Apple, to discuss Apple's next product the day before his death, according to Masayoshi Son, CEO of Softbank, who was meeting with Cook at the time.

In an interview with U.S. Ambassador to Japan John Roos, Son said that he was visiting Apple's headquarters in California on the day the company announced the iPhone 4S.

Oh Masa, sorry, I have to quit our meeting, Cook told Son. Steve is calling me because he wants to talk about the next product.

That next product has been rumored to be the iPhone 5.

That's the kind of spirit a true entrepreneur would continue to have until they die. He was very sick, very ill. But the announcement of their newest product made him live longer, said Son. Physically he could have died much earlier. But his passion, his love for his own company and dream, about the next products, that made him energized.
